The inventive concept has features in that the left and right shoelace engaging members 20 and 30 are provided at the left and right sides of the upper portion of the shoe front upper 60 so as to engage the shoelace 10. The left and right shoelace engaging members 20 and 30 comprise fixed members 22 and 32 connected to the shoe front upper 60, and movable members 24 and 34 which are rotatably attached to the fixed members 22 and 32 and the hinges 23 and 33. Two left and right shoelace engaging members 20 and 30 may be installed on the shoe front upper 60 in a symmetrical fashion at left and right sides, respectively. However, the number of the left and right shoelace engaging members 20 and 30 are not limited thereto. The number of the left and right shoelace engaging members 20 and 30 may be one or more than two.

Holes 21 and 31, through which the shoelace 10 passes, are formed at the one ends, for example, front end, of the movable members 24 and 34 of the left and right shoelace engaging members 20 and 30. The movable members 24 and 34 rotate about the fixed members 22 and 32, thus adjusting the distance between the holes in the left and right shoelace engaging members 20 and 30. In a state that the movable member is folded, the distance between the holes in the left and right shoelace engaging members 20 and 30 is shortened, which helps loose the shoelaces. In a state that the movable member is unfolded, the distance between the left and right shoelace engaging members 20 and 30 becomes longer, which helps tighten the shoelace. The tension being applied to the shoelace 10 can be adjusted in such a way to fold or unfold the movable member.

In addition, the main shoelace engaging member 40 is disposed between the left and right shoelace engaging members 20 and 30 of the upper most portion of the shoe front upper 60. The main shoelace engaging member 40 comprises a main fixing member 41 which is fixed at the tongue 70 engaged to the font open portion of the shoe front upper 60, and a main movable member 43 which is rotatably engaged to the main fixing member 41 by means of the main hinge 42. The shoelace 10, which passes through a gap 44 formed between the main fixing member 41 and the main movable ember 43, can be tightened to or loosened from the bottom of the main movable member 43 by rotating the main movable member 43 which rotates about the main hinge 42 of the intermediate portion.

The first Velcro 50 a, one of Velcro hooks and Velcro loops, is connected to the end of the shoelace 10 which passes through the main shoelace engaging member 40, and the second Velcro 50 b, the other of the Velcro hooks and the Velcro loops, is fixed to the tongue 70. The end portion of the shoelace can be detachably connected to the tongue 70 by attaching the first Velcro 50 a to the second Velcro 50 b.

The left and right shoelace guide engaging members 80 and 90 can be engaged to the bottom portion of the shoe front upper 60. The left and right shoelace guide engaging members 80 and 90 are disposed below the left and right shoelace engaging members 20 and 30. Guide holes 81 and 91 are formed at ends of the left and right shoelace guide engaging members 80 and 90, so the shoelace 10 passes through the guide holes 81 and 91.

The insertions of the shoelace into the shoe will be descried according to the inventive concept. When the shoelace 10 is inserted into the shoes, one end of the shoelace 10 is forced to pass through the hole 21 of the left shoelace engaging member 20, and the other end of the shoelace 10 is forced to pass through the hole 31 of the right shoelace engaging member 30. After passing through all the holes 21 and 31 of the left and right shoelace engaging members 20 and 30, which are positioned at the upper portions of the shoe front upper 60, both ends of the shoelace are forced to pass through the gap 44 of the main shoelace engaging member 40. The main shoelace engaging member 40 is first fastened so that the shoelace 10 is not loosened while maintaining a comfortable condition with shoes. The left and right shoelace engaging members 20 and 30 are unfolded to adjust the tension applied to the shoelace 10.

The inventive concept has advantageous effects in that the tension being applied to the shoelace can be properly adjusted in such a way to fold or unfold the left and right shoelace engaging member and the main shoelace engaging member of the shoe, and the shoelace is easily loose or tighten to adjust the tension applied to the shoelace of the shoe.

The engagement of the fixed member 22 and 32 and the movable member 24 and 34 of the inventive concept will be described.

The hinge hole into which the hinge 23 and 32 is inserted, may have an oval shape, more specifically, a horizontal axis is longer than a vertical axis. The hinge hole includes front arc surfaces 25 and 35, and rear arc surfaces 26 and 36. The shoe, enabling the adjustment of the tension of shoelaces in which left and right shoelace engaging members 20 and 30 configured to engage a shoelace are provided at left and right sides of the upper portion of a shoe front upper 60, comprise improved left and right shoelace engaging members 20 and 30 which include fixed members 22 and 32 engaged to the shoe front upper 60, and movable members 24 and 34 rotatably engaged to the fixed members 22 and 32 by means of hinges 23 and 33. Holes 21 and 31 through which a shoelace passes 10 are formed at the one ends, for example, front ends, of the movable members 24 and 34. The movable members 24 and 34 rotate about the fixed members 22 and 32, thus adjusting the distance between the holes 21 and 31 formed at both ends of the left and right shoelace engaging members 20 and 30, thereby adjusting the tension being applied to the shoelace 10. The hinge hole of the fixed member 22 and 32 into which a hinge 23 and 33 is inserted may have an oval shape, more specifically, a horizontal axis is longer than a vertical axis, and the hinge hole includes front arc surfaces 25 and 35, and rear arc surfaces 26 and 36.

When the shoelace 10 is tightened, the movable members 24 and 34 move in the forward direction by the tension which is applied to the shoelace, and the hinges 23 and 33 inserted in the hinge holes move in the forward direction and come into close contact with the front arc surfaces 25 and 35 formed in the hinge holes of the fixed member and thereby the movable members 24 and 34 are fixed. The hinge 23 and 33 formed in the movable member are smaller than the hinge holes formed in the fixed member 22 and 32.

When the shoelace is loosened, the tension is not applied to the shoelace, so the hinges 23 and 33 can be freely movable in the interiors of the hinge holes.

The engaging protrusions 27 and 37 are formed on the front surfaces of the movable members 24 and 34, and the engaging grooves 28 and 38 are formed on the back surfaces of the fixed members 22 and 32. When the shoelace is tightened, the front surfaces of the movable members 24 and 34 contact with the back surfaces of the fixed member, so the engaging protrusions of the movable member are hooked in the engaging grooves of the fixed member, thus obtaining reliable fixing.

In the inventive concept, the movable member lower surface protrusions 29 and 39 may be further formed on the bottoms of the movable members 24 and 34, and the fixed member upper surface protrusions 29′ and 39′ may be formed on the tops of the fixed members 22 and 32. When the shoelace is tightened, the front surfaces of the movable members 24 and 34 come into close contact with the back surfaces of the fixed members 22 and 32, so the movable member lower surface protrusions 29 and 39 of the movable members 24 and 34 are hooked by the fixed member upper surface protrusions 29′ and 39′ of the fixed members 22 and 32, thus obtaining reliable fixing.

The fixed members 22 and 32 are fixedly attached to the upper portion of the shoe front upper 60. Attachment holes 101 and 301 are formed at the fixed members 22 and 32, and the fixed pins 109 and 309 are inserted into the attachment holes 101 and 301 and are tightly fixed. At least two attachment holes may be formed at the fixed member.

The inventive concept has features in that the tension being applied to the shoelace can be easily adjusted by folding or unfolding shoelace engaging member and the main shoelace engaging member of the shoe while easily loosening or tightening the shoelace. In addition, the tension of the shoelace can be more reliably adjusted in such a way to widen the left and right shoelace engaging hinge holes of the shoe and to form the engaging protrusions at the movable member and the engaging groove at the fixed member, respectively.
